I am trying to run a power flow in PowerModels.jl by using Newton method. I am running compute_ac_pf, but the result of this function is a dictionary containing generation and voltages at the buses, and it does not have a key “solution”. However, I am also interested in obtaining the flows in the lines of the system. Is there any way I can get these results? I am using version 0.17 of PowerModels.jl.
Thank you, @odow and @ccoffrin !! I updated my code to v0.18 of PowerModels.jl and it worked. However, I noticed that when I run the generic power flow, by using the run_pf function with the ACRPowerModel formulation, the calc_branch_flow_ac function doesn’t return updated values for the branch flows. When I use the run_pf function with the ACPPowerModel formulation, or directly the run_ac_pf function, I am able to obtain the correct values for the branch flows. Here is my code:
using PowerModels
using Ipopt
network_data = parse_file("/Users/marianarodrigues/Desktop/Sistema Inicial/teste_novo.raw")
print_summary(network_data)
# ========================= JuMP solution =========================
#result = run_ac_pf(network_data, Ipopt.Optimizer)
result = run_pf(network_data, ACRPowerModel, Ipopt.Optimizer)
# Check that the solver converged:
update_data!(network_data, result["solution"])
flows = calc_branch_flow_ac(network_data)
update_data!(network_data, flows)
print_summary(network_data)
